Corrections and clarifications

A feature on the architecture of the Athens Olympic Games mentioned graffiti in the city highlighting 18 deaths during construction (Stadium of the gods, G2, page 10, August 2). This information was in a paragraph explaining "rumours of catastrophic failure" during the building of the roof of the main stadium designed by the architect and engineer, Santiago Calatrava. Representatives of Mr Calatrava have asked us to point out that they are not aware of a single death to date at the stadium site. The deaths - estimated to number between 14 and 40 - are thought to have occurred at other construction sites in the city.

George W Bush was born in Connecticut and educated in a Massachusetts boarding school and then at Yale University, also in Connecticut. So we were a little wide of the mark in claiming he is "a Texan, born and brought up in America's oil state" (Oil and troubled waters, Review, page 7, July 31). Texas can claim two native-born presidents, Dwight Eisenhower and Lyndon Johnson.

We said in error that the new digital closed circuit TV system at Luton airport had been installed by a company called Dedicated Micros when the contractor was Intruder International plc. Apologies (Eye spy with my little network, Online, page 17, July 22).

Our report of a bomb attack carried the misleading headline, in early editions, Five Britons injured in Prague bombing, when the copy explained that "five tourists from Britain and Ireland" had been among the injured. This was amended in later editions to read: Britons among 18 injured by Prague blast (page 11, August 2).
